DTC P0108-00: Map Sensor Circuit High Input: Notes
DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0108:00 |
MAP sensor circuit high input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the MAP sensor. If the input voltage at the PCM terminal 1BW is above 4.89 V
for 5 s
, the PCM determines that the MAP sensor circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Estimates MAP using MAF sensor and engine speed.
- Restricts the upper limit of the engine speed.
- Inhibits the evaporative purge control.
|
| POSSIBLE CAUSE |
- MAP sensor/IAT sensor No.2 connector or terminals malfunction
- PCM connector or terminals malfunction
- MAP sensor malfunction
- Short to power supply in wiring harness between MAP sensor/IAT sensor No.2 terminal D and PCM terminal 1BW
- Open circuit in wiring harness between the following terminals:
- MAP sensor/IAT sensor No.2 terminal D-PCM terminal 1 BW
- MAP sensor/IAT sensor No.2 terminal A-PCM terminal 1BX
- PCM malfunction
